// The implementation handles the 32-bit rollover (every 49.7 days) by:
|

// 1. Using a lock when detecting rollover to ensure atomic update
|

// 2. Restricting normal updates to forward movement within the same epoch

// This prevents race conditions at the rollover boundary without requiring
|

// 64-bit atomics or locking on every call.

// Single-core platforms have no concurrency, so this is a simple implementation

// that just tracks 32-bit rollover (every 49.7 days) without any locking or atomics.
